Pre-Workout Booster Briefly Explained

The market for training boosters is huge – but the basic principle is always the same: a powder mixture, prepared about 20–30 minutes before training. Differences lie in three dimensions: the amount of caffeine (from caffeine-free to highly dosed), pump ingredients like citrulline and arginine, and ingredients for taste and focus. The caffeine content per serving is on the label – it is the most important selection criterion, especially if coffee or energy drinks are already consumed during the day. Those who train late or are sensitive to caffeine will find a suitable alternative in stimulant-free pump products.
